target launch window once requirements are clear
Outlook inboxes included per domain package
Google Workspace for quality, Microsoft 365 for scale

Do not compare only per-inbox price. Compare setup reliability, replacement path, provider mix, and how fast a real person can help when a launch is blocked.
Provider mix
Google for quality and Outlook for scale.
Replacement policy
Know what happens when an inbox or domain gets damaged.
Launch support
Setup speed matters when campaigns are ready to go.
When To Consider A Mailforge Alternative
Mailforge positions around cold email infrastructure sorted quickly, distributed email infrastructure, automated DNS, API/MCP/CLI access, compatibility with Salesforge and other sending tools, and pricing that drops by volume.
What Mailforge Already Does Well
- Distributed infrastructure is the core public angle
- The product emphasizes setup in minutes
- DMARC, SPF, DKIM, and custom tracking are presented as standard setup items
- Pricing examples show lower per mailbox pricing at scale
When An Alternative Makes Sense
Avoid choosing Mailforge just because of low unit cost if you have not mapped domains, inboxes, and daily send limits.
Before Replacing Mailforge, Check These First
Switching providers is not like changing a landing page tool. Domains, inboxes, warmup, sequencer connections, and reputation all move slowly.
Domain architecture
Ask how many domains are created for your target volume
Tracking domains
Ask whether custom tracking domains are configured per client or globally
Automation access
Ask whether API/CLI access matters for your workflow or is just nice to have
Replacement policy
Ask what mailbox replacement SLA exists
Domain architecture
Ask how they prevent overloading new domains
Operational Checks Before You Switch
Mailforge is a direct infrastructure alternative. The useful comparison is support model, provider coverage, and how safely campaigns can scale.
Choose Mailforge if its platform workflow fits your current ops. Choose ScaledInboxes if you want managed sizing and setup around campaign goals.

How replacements are handled
Plan infrastructure by usable sending capacity.
Cheap inboxes get expensive when DNS is wrong, replacements are unclear, or campaigns sit blocked. Price the system, not just the mailbox.
- Best for low-cost scale
- Useful for provider diversification
- Requires conservative send limits
- Best for Gmail-heavy audiences
- Higher-quality lane for valuable accounts
- Use controlled ramp-up, not brute force
Setup quality
SPF, DKIM, DMARC, MX, forwarding, and sequencer connection need to be right before volume starts.
True cost
Warmup time, replacement policy, support, and DNS mistakes change the real cost per usable inbox.
Best fit
Built for operators who want managed infrastructure and fast human help across multiple campaigns.
How to choose the right inbox setup
Use the provider mix as a portfolio decision. One lane gives simplicity. Two lanes give resilience.
Use Google Workspace when
- Your prospects are Gmail-heavy.
- Placement quality matters more than lowest unit cost.
- You are running smaller, higher-value campaigns.
Use Microsoft 365 when
- You need lower-cost scale.
- You want provider diversification.
- You can spread volume conservatively across many inboxes.
Common questions
How many inboxes do I need?
Start conservative. Use the calculator to map daily send goals into inbox count, domain count, and provider mix.
Should I use Google Workspace or Microsoft 365?
Google is stronger for Gmail-heavy audiences. Microsoft 365 can lower cost and diversify infrastructure. Serious operators often use both.
What matters more than price?
DNS accuracy, send limits, replacement policy, support speed, and domain isolation matter more than saving a few cents per inbox.
Need this sized for a real campaign?
Send daily volume, number of campaigns or clients, provider preference, and sequencer. We’ll map inboxes, domains, and monthly cost.
